Description
Technical field
This utility model relates to electric automobile lithium battery field, particularly to a kind of Bidirectional-squeezing fastening structure.
Background technology
Electric automobile lithium battery, because of plurality of advantages such as its life-span length, environmental protection, has become as the sophisticated industry in this field. Through development for many years, raising gradually along with quality Yu technique, the life-span of battery and ruggedness obtain significantly high lifting, and, prove through long-term operation, the overall quantity of operation of lithium battery, not only relevant to the quality of cell, more closely bound up with the packaging technology of lithium battery in groups, structure. Effectively promoting the structural quality of integral battery door group, the development to lithium battery is very important link. Traditional lithium battery group, when in package assembly, design is fixing, often adopt the structure that one-way compression is fixing, steel plate and compressing structure in this structure serve certain fastening effect, but the problem due to terminal car product difference road conditions, battery modules is with automobile together play or left and right vibrations up and down, along with long-term motion circulates so that battery modules appearance is loose waits loose contact etc. even to jeopardize safety problem. The connectivity of whole Battery pack worse and worse, ultimately results in the life-span of whole Battery pack, quality safety is greatly affected. Make it cannot use on the road conditions of condition difference.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the problems referred to above, it is provided that a kind of Bidirectional-squeezing fastening structure that can better realize locking function.
To achieve these goals, the technical solution adopted in the utility model is such that Bidirectional-squeezing fastening structure of the present utility model, including voussoir, voussoir has through hole, through hole is two, voussoir is positioned at a voussoir locking support plate, voussoir locking support plate has through hole, its through hole mates with the hole size on voussoir, voussoir locking support plate adopts two plate bodys to be spliced, through hole on voussoir locking support plate is arranged on two plate body stitching portions, voussoir is connected with voussoir locking support plate by the fastening bolt being arranged in its through hole, voussoir locking support plate both sides are separately installed with the first push pedal and the second push pedal, first push pedal and the second push pedal are close-coupled on voussoir locking support plate.
Further, as a kind of concrete version, voussoir described in the utility model adopts plastic cement material to make.
Further, as a kind of concrete version, fastening bolt Surface coating described in the utility model has resistant to rust material structure layer.
Further, as a kind of concrete version, voussoir locking support plate Surface coating described in the utility model has oxidation-resistant material structure sheaf.
Compared with prior art, the utility model has the advantage of: Bidirectional-squeezing fastening structure of the present utility model can better realize locking function, while utilizing bolt-locking, two ends push pedal is extruded to two ends, thus reaching the purpose of locking, and battery modules in the horizontal direction above time, can better be fixed, substantially increasing safety and reliability, battery also can effectively be extended.
